BUTTON FASTENER.

Application filed March 7, 1925.

To all whom it may concern:

Be it known that 1, PETER GnuNs'rRA, a citizen of the United States,residing at Clifton, in the county of Passaic and State of New Jersey,have invented certain new and useful Improvements in Button Fasteners,of which the following is a specification.

This invention relates to improvements in button fasteners, and moreparticularly to an improvement over my button fastener embodied in mycopending application, bearing Serial No. 4,792, filed January 26, 1925.

One of the important objects of the present invention is to provide abutton fastenor wherein means is provided for securing the buttonfastener on a garment against accidental displacement therefrom.

A further object is to provide a button fastener which may be easily andquickly assembled 0r secured on a garment without using any sewingthread.

Other objects and advantages of this in vention will become apparentduring the course of the following description.

In the accompanying drawing, forming a part of this specification, andin which like numerals indicate corresponding parts throughout theseveral views:

Figure l is a view, partly in elevation, and partly in section of thebutton fastener embodying my invention, showing the same in assembledrelation.

Figure 2 is a sectional view, tpken approximately 011 the line 22 ofFigure 1.

Figure 3 is a top plan view of the upper disc showing the inner adjacentends of the locking pins, and

Figure l is a detail perspective view of one of the locking pins.

In the drawing, wherein for the purposeof illustration is shown thepreferred embodiment of my invention, the numeral 1 designates a buttonof any conventional construction, the same being provided with thelooped shank portion 2. The fastener comprises the ring like member 8formed of resilient material, the free ends 4: and 5 re spectivelythereof, being disposed in parallel abutting relation. The paralleldisposed free end portions l and 5 are provided with the notches 6 and 7respectively, and the purpose thereof will be presently apparent. I

The holder for the ring like member 3 Serial No. 13,801.

comprises a cylindrical member 8, the same being provided with a centralopening 9, in which is adapted to be disposed the parallel abutting freeend portions 4 and 5 of the ring like member 3. The opening 9 issubstantially oval-shaped as clearly illustrated in Figure 2 of thedrawing. The cylindrical member 8 is further provided with a pair ofdiametrically opposed openings 10 and 11 respectively, the openingsbeing disposed horizontally and communicating at their inner ends withthe central opening 9. The outer ends of the openings are slightlyenlarged, as clearly illustrated in Figure 2.

A pair of locking pins are adapted for slidable movement within therespective horizontally extending openings. Each of the locking pins isof substantially T-shaped design. The shank or leg portion of each ofthe substantially T-shaped locking pins is bevelled at its free ends, asillustrated at 14. The locking pins 12 and 13, which are disposed withinthe openings 10 and 11 respectively will have their inner opposedbevelled ends cooperating with the notches 6 and '7 respectively, forlocking the free end portions of the ring like member 3 in thecylindrical holder 8. The arms of each of the T-shaped locking pins areadapted for movement within the enlarged outer ends of the horizontallyextending openings.

A fiat spring band 15 extends around the peripheral edge of thecylindrical holder 8, the free ends of said spring band being arrangedin overlapping relation. he spring band 15 engages the head portions ofthe 'l'shaped locking pins and normally urges the latter into lockedengagement with the notches provided in the free end portions eland 5 ofthe ring like member. It is of course to be understood that when thering like memberis assembled with respect to the cylindrical holder, thebevelled lower ends of the free end portions will engage the bevelledfaces l l of the T-shaped locking pins and move the same outwardlyagainst the tension of the flat spring band 15, so as to permit theparallel abutting free end portions of the ring like member to bedisposed within the central opening 9 of the cylindrical holder. 7

Then the notches 6 and 7 are in alignment with the inner ends of thellLOl'lZOlltill ly extending openings, the bevelled inner ends of theslidable locking pins will be forced into engagement with the respectivenotches, thereby securely holding the ring like member in positionwithin the cylindrical holder 8.

The means for securing the holder 8 on a garment comprises the upper andlower discs 16 and 17 respectively. The lower disc 17 is formed on thebottom of the cylindrical holder 8, whereby a unitary structure isprovided; the upper disc 16 being adapted to engage the upper face ofthe holder. In attaching the holder on a garment, it is of course to beunderstood that a suitable opening is formed in the garment forreceiving the cylindrical holder 8. The discs, which are formedpreferably of sheet metal and are of a greater diameter than thediameter of the cylindrical holder 8 are clearly illustrated inFigure 1. Furthermore, the discs are provided with central registeringopenings which are of the same shape as the central opening 9 formed inthe cylindrical holder 8, these openings being in registry with eachother, so as to permit the ready and easy insertion of the free endportions at and 5 of the ring like member with respect thereto. Theedges of the discs 16 and 17 are provided with the protuberances 18 and19 respectively, the same being struck out from the discs. Theseprotuberances form gripping teeth, and are adapted for engagement withthe material of the garment on which the button is to be fastened. Theteeth 18 formed on the upper disc 16 are disposed between the teeth 19formed on the lower disc 17, the gripping teeth being further arrangedin annular spaced relation on each of the discs. The upper plate 16 isadapted to be disposed adjacent the outer side of the cloth, whereas thelower plate 17 en gages the opposite side of the cloth.

It will thus be seen from the foregoing description that a buttonfastener has been provided, wherein the parts are of such constructionas to enable the same to be readily and easily assembled and secured ona garment, without using sewing thread, such as is commonly used insecuring a button on a garment. The simplicity with which the presentdevice is constructed, renders the same inexpensive in its manufacture,yet strong and durable.

While I have shown the preferred embodiment of my invention, it is to beunderstood that various changes in the size, shape, and arrangement ofparts may be resorted to, without departing from the spirit of theinvention or the scope of the appended claims.

hat I claim is:

1. In a fastener for a button, wherein the latter is provided with alooped shank por tion, a resilient ring like member adapted to receivesaid looped shank portion, the free ends of said ring like member beingdisposed in parallel abutting relation, a
